RE: Why can't I default Originate?
Thanks HC, Two things. I was told this was not a topic for this list. Sorry about that. Since I've already posted, I think I should post what the problem was. Problem=I'm stupid. I wasn't looking in the right place for what I was advertising. I ran: router#sh ip bgp nei 10.99.200.75 adv BGP table version is 43, local router ID is 10.1.80.44 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale Origin codes: i - IGP, e - EGP, ? - incomplete Originating default network 0.0.0.0 Network Next Hop Metric LocPrf Weight Path *> 22.214.171.124/24 126.96.36.199 0 32768 i router# I was looking for the network, but not the line that stated: Originating default network 0.0.0.0 So it was advertising and I've verified it on the remote peers (which I should have done first!). Still doesn't answer why CISCO says you apply default orig to the peer, not the peer group (which we've proven is backwards). It shouldn't be this way since you may want to use the peer group as a template for multiple customers, but they may not all want 0/0 sent to them. ALSO I didn't need to have 0/0 in my local routing table nor did I need to add the BGP command "Synchronization." According to CISCO (which is actually accurate), it will originate default UNCONDITIONALLY, which it does. I'm still concerned about applying the command to the peer vs. the peer group issue. Sorry about having posted this to Nanog, I'll filter my future questions more carefully. Thanks for everyone who answered! -=Vandy=- -----Original Message----- From: Haesu [mailto:[email protected]] Sent: Tuesday, July 08, 2003 2:04 PM To: [email protected] Subject: Re: Why can't I default Originate? After you applied default-originate to peer-group, have you done soft-clear of your bgp session? It usually takes a little while for changes in config to propagate, unless you force an update using soft clear... -hc -- Sincerely, Haesu C. TowardEX Technologies, Inc.
